area. Return the top bead breaker unit to the rest position by operating the mobile
lever underneath the arm of the unit by hand from the operator side - 11 fig. 8a.

- The bottom bead breaker unit is already in the ideal radial position for breaking the

bead on the underside of the tyre. Operate

the

Lever

2 fig. 9b to bring the disc into

contact with the tyre.

- Press the

Pedal

1 fig. 9c and operate the

Lever

2 fig. 9b so that the disc penetrates further

into the wheel. The bead breaker disc is inserted into the wheel as it rotates to com-
pletely separate the bottom bead of the tyre from the rim.

- Operate

the

Lever 2

fig. 9b to return the entire unit downward, removing it from the

working area.

- Remove any old balancing weights from the rim.

TYRE DEMOUNTING

- Make sure that you have lowered the lower bead breaker.

- When working on stiff, difficult tyres the tyre should be lubricated carefully along the

whole circumference of the top and bottom beads to simplify demounting and prevent
damage to the beads (fig. 14). Lubricate with specific products and do not use oily
solutions containing hydrocarbons or silicones.

- With the tool head at the start of its travel stroke, meaning that it is above the wheel

and away from the working zone, if necessary push or pull the

Button

4 fig. 9b to prepare

the mobile tool 1 fig. 15 to demount the top bead of the tyre.

- Operate the

Lever

7 fig. 9b to move the mobile tool forward to its limit position in the

direction of the wheel, and lower it until it is almost touching the top bead (fig. 15a).

- Completely lower the mobile tool beyond the shoulder of the rim (fig. 15b). Now press

the

Button

5 fig. 9b to obtain a grip on the top bead of the tyre (fig. 15c). If necessary, turn

the wheel to allow this by pressing

Pedal

1 fig. 9c. Once the grip has been established

release the button to return the tool to its rest position (fig. 15d).

- Operate the

Lever

7 fig. 9b and raise the mobile tool, gripping the tyre, until the whole

of the groove on the tool can be seen beyond the rim (fig. 15e and A fig. 16).

- Turn the

Switch

6 fig. 9b fully down. The mobile tool gripping the top bead moves away

from the centre of the wheel, lifting the tyre beyond the rim (fig. 15f). At the same time
the turntable moves towards the taut part, releasing the tensions generated in the
structure of the tyre. Keeping the

Switch

6 fig. 9b turned, press the turntable rotation

Pedal

1 fig. 9c to demount the top part of the tyre from the rim.

- Once the top bead has been demounted release the

Switch

6 fig. 9b to return the mobile

tool to its rest position and the

Pedal

1 fig. 9c to stop rotation of the wheel.

- Operate the

Lever

7 fig. 9b to remove the mobile tool from the working area. The tool

head must be lifted away from the wheel and moved completely back.

- If the tyre has an inner tube, after demounting the top bead remove the inner tube

before proceeding to demount the bottom bead. If necessary, turn the wheel slightly
to facilitate this by pressing

Pedal

1 fig

9c. Rotation of the turntable can be stopped at

any moment by releasing its control pedal. To rotate in the opposite direction, simply
raise the pedal.

- Press

Lever

9 fig. 9b up to operate the pneumatic support and bring the supporting ele-

ment into contact with the underside of the tyre. Press until the underside of the tyre
has been raised to about the height of the rim’s top shoulder.

- Operate the

Lever

7 fig. 9b to guide the tool head into the working zone to demount the
